Hi menglxs, Zebras has directed here from another post - that’s why I didn’t post earlier.
I found that the sounds quality of DSL v5a adult fitting formula was good, but changing fitting formulas would affect all programs.
If I changing the compression type under Global tuning to semi linear or linear, sound quality will improves, but changes can affect all programs.
You are right, changes in basic adjustments CAN affect all programs. But it needs not to do so. You can change basic settings but don’t let “Target” to recalculate the fitting parameters. Then you have the old properties for all present programs.
If you add a new program or instruct a specific program within “finetuning” to recalculate, then that program/s will receive the new properties from the basic tunings.
Btw: I have an S-slope hearing loss. Linear amplification is a bad idea.
Linear amplification may be worth to try if one has almost the same loss on all frequencies.
This Phonak target programming course has some suggestion for the music programs.

Thank you for the link.
Fun-fact from the pdf (page 4): Patient reports: “I can hear people far away better than I can hear people close to me.” Solution: reduce soft-sounds.
The result is: You no longer can hear people far away as good as you did before, it is worse.
